Celestial Pearl Danio

Celestial Pearl Danio (Danio margaritatus)

The Celestial Pearl Danio, often called the Galaxy Rasbora, is one of the most stunning nano fish in the freshwater aquarium hobby. This remarkable species features a deep blue body covered in pearly white spots, resembling a star-filled night sky. Combined with vibrant red-orange fins, its unique coloration has made it a favorite among aquascapers and planted tank enthusiasts around the world.

Native to small ponds and wetlands in Myanmar, Celestial Pearl Danios thrive in heavily planted aquariums with plenty of cover and open swimming areas. Their small size makes them ideal for nano aquariums, while their striking appearance allows them to stand out even in larger planted displays. Males develop the most intense coloration and often display to one another, creating fascinating social interactions within the aquarium.

These peaceful fish are best kept in groups, where they become more confident and display natural schooling behavior. They readily accept high-quality micro pellets, crushed flakes, frozen foods, and other appropriately sized diets. Their calm temperament makes them excellent tank mates for shrimp, small rasboras, Corydoras, and other peaceful nano species.
